He's also a super-user of Dropbox, paying for its premium
functions because he found the product so useful and reliable.

But as a designer and developer, his Dropbox files numbered into
the thousands. He writes on Medium:

As time went on, I ignored the security gossip and really
committed, I put everything into that folder, safe in the
knowledge it was all going to seamlessly work. But the more I
stored in my Dropbox, the more problems I had.

At first there was few mis-syncs, a few stuck files and a bit of
“Dropbox: 129%” utilisation in Activity Monitor, but over the
last few months it’s got really bad. Dropbox hangs with a full
core being utilised for hours. New syncs don’t finish at all.
Time to talk to support…

At that point he found this web page on Dropbox's web site, which
states that Dropbox starts to fail once you dump more than
300,000 files into it:

We emailed Dropbox to see if they wanted to elaborate. We'll
update this post if we hear from the company.

A 300K file limit won't affect most users, of course. And the
free account with a limit space for uploads is fine for most
ordinary users.
